Dual set point air switch (LF40-02P)

LF40-02P switch utilizes two high-quality miniature snap-action switches with higher current capacity, SPST or SPDT contact form and switch deadbands (also referred to as mechanical differntial or hysteresis). The switch is diaphragm operated. Diaphragm material can be selected according to the operating medium, temperature range and other parameters.
LF40-02P pressure switch can control the s
Extend duty pressure switch (LF20)

The LF20332 pressure switch is specifically designed to stand up to extended duty applications. This switch is factory set but capable of field adjustment. It features different diaphragms for compatibility with a wide variety of fluids, and various terminations including a Metri-Pack connector that forms a tight seal when connected. Among the outstanding design benefits are its durable constructi
Air Switch for spa, food waste disposer (LF40)

LF42 air switch is pressure switch adapted to be used together with air button (also called as Actuator) for remote control purpose. It is widely used in food waste disposer, pumps for swimming pools and spas, hot tubs, sanitary equipment, out door machines, medical equipment etc. As a remote control switch, it is small enough to fix in the control box of the engine.
Media:Non hazardous gas;
pressure switch for steam iron & steam cleaner (LF25)

LF25 pressure switch is designed for control pressure with higher current capacity.It is widely used in steam cleaner, steam sadiron and other pressure control system. It provides SPST or SPDT contact form and switch deadband (also referred to as mechanical differential or hysteresis).
Pressure Range: 0.2-9 Bar;
Electrical Rating: SPST or SPDT/ Normal Close: 16(4) A-250VAC;
Operating Temperat
pressure switch

The LF20332 pressure switch is specifically designed to stand up to extended duty applications. This switch is factory set but capable of field adjustment. It features a Kapton diaphragm for compatibility with a wide variety of fluids, and various terminations including a Metri-Pack connector that forms a tight seal when connected. Among the outstanding design benefits are its durable construction
air sensing switch

The AFS is a general purpose airflow proving switch designed for HVAC, detection of blocked filters and fan suction, air flow monitoring in ducts, pipes, tunnels, and other energy management applications. It may be used to sense positive, negative or differential air pressure.
air sensing switch

The LFAS employs a differential pressure to actuate a precision snap switch at chosen pressure setting. This may be the difference between atmospheric and a negative or positive pressure or between any two given pressures. When a change of pressure occurs between the negative pressure chamber and the positive pressure chamber the main diaphragm activates the snap switch at a pre-determined value.
pressure control for PCB

LFS-02 Pressure Switch is designed as an economical interface between pressure systems and Printed Circuit Boards. This switch can be used as a gauge or differential pressure switch with almost no hysteresis. It is applied to detection both positive and negative pressure. Features of this switch include a body design that allows the pressure ports to be rotated, various terminal styles including w
pressure switch for compressor

The LF10 pressure switches are used to regulate the tank pressure between two preset values on small (up to 175psi) electrically driven air compressors. They are available with an unloader valve, which prevents compressors from starting under load, and an auto-off disconnect lever for manual cut off the compressor. A four port manifold style is available which provides a means for easy mounting
vacuum switch

LFS-01 vacuum pressure switch is applied to detection of negative pressure, such as the family vacuum cleaner. It is provide solder pin connections and is especially designed for mounting on "Printed Circuit Boards". It is designed as an economical interface between pressure systems and Printed Circuit Boards with almost no hysteresis.
